Attractant Effect of Female Preputial Gland Extracts on the Male Rat.

摘要

(1) Female rat preputial glands contained volatile ether soluble substances, which were attractive to male rats. (2) Male rats preferred the odor of preputial glands from intact females or from ovariectomized females treated with estrogen and progesterone to the odor of gland extracts from ovariectomized females. (3) Extraction of attractive components with different solvents revealed biological activity which was connected with relatively nonpolar, volatile lipid substances. Fatty acids were excluded as active components. (4) The volatile lipids were partially analyzed by gas chromatography and the active compounds were found in a specific fraction. (Author)
